The AI developer Anthropic has confirmed it is investigating a report that unauthorised users have gained access to its Mythos model, which it has warned poses risks to cybersecurity,The US startup made the statement after Bloomberg reported on Wednesday that a small group of people had accessed the model, which has not been released to the public because of its ability to enable cyber-attacks,“We’re investigating a report claiming unauthorised access to Claude Mythos Preview through one of our third-party vendor environments,” said Anthropic,Bloomberg said a “handful” of users in a private online forum gained access to Mythos on the same day Anthropic said it was being released to a small number of companies including Apple and Goldman Sachs for testing purposes,It reported that the unnamed users got to Mythos through access that one of them had as a worker at a third-party contractor for Anthropic and by deploying methods used by cybersecurity researchers.

The group has not run cybersecurity prompts on the model and is more interested in “playing around” with the technology than causing trouble, according to Bloomberg, which corroborated the claims via screenshots and a live demonstration of the model,Nonetheless, news of the potential breach will alarm authorities who have raised concerns about Mythos’s potential to wreak havoc and will raise questions about how potentially damaging technology can be kept out of the wrong hands,Kanishka Narayan, the UK’s AI minister, has said UK businesses “should be worried” about the model’s ability to spot flaws in IT systems – which hackers could then act upon,The model has been vetted by the world’s leading safety authority for the technology, the UK’s AI Security Institute (AISI), which warned last week that Mythos was a “step up” from previous models in terms of the cyber-threat it posed,AISI said Mythos could carry out attacks that required multiple actions and discover weaknesses in IT systems without human intervention.

It said these tasks would normally take human professionals days to carry out,Mythos was the first AI model to successfully complete a 32-step simulation of a cyber-attack created by AISI, solving the challenge in three out of its 10 attempts,

The Hours won awards for Nicole Kidman’s fake nose – and hearts as a queer classic

Michael Cunningham’s Pulitzer prize-winning book The Hours – inspired by Virginia Woolf’s seminal 1925 novel, Mrs Dalloway – imagines one day in the lives of three women separated across time periods. The triptych follows Woolf in the throes of writing Mrs Dalloway; Laura Brown, a depressed housewife who is reading Woolf’s novel in postwar America; and Clarissa Vaughan, a New Yorker who acts as a contemporary embodiment of Woolf’s titular character.Cunningham’s 1998 text, though widely acclaimed, was initially deemed unadaptable due to its nonlinear structure and stream-of-consciousness approach that paid homage to Woolf’s pioneering style. However, since its publication, The Hours (which takes its name from Mrs Dalloway’s working title), has been reinterpreted as an opera and, most notably, a 2002 film directed by Stephen Daldry.As the title suggests, the film explores the ways in which the routine of a single day can be at once beautiful in its ordinariness or seismic in its oppressive mundanity

Vanessa’s a pillar of the hiking community | Brief letters

Your report (Campaigners seek listed status for historic trig points that mapped Britain, 16 April) didn’t mention the Vanessa trig point – Vanessa being a corruption of the Venesta company, which made cardboard tubes into which the concrete for the pillars was poured. These were designed for less accessible places, mostly in the Scottish Highlands and Islands.

V&A East Storehouse and Norwich Castle among finalists for museum of the year

The V&A East Storehouse, the National Gallery and an accessible castle in Norwich are among the contenders for this year’s Art Fund museum of the year award, the most prestigious UK prize in the sector.The annual prize offers the winner £120,000, with £20,000 going to each of the other finalists, who the Art Fund’s director, Jenny Waldman, said had all “innovated in different ways”.This year’s list is dominated by some of the biggest names in the cultural sector that have undergone big refurbishments or invested in significant new outposts, such as the V&A’s East Storehouse, which will be seen by many as a frontrunner.Based in the Olympic Park in Stratford, east London, the space aims to reimagine what a storeroom can be, with partitions removed so visitors can see “and breathe the same air” as the objects. Waldman said the V&A Storehouse, which opened in spring 2025 at a cost of £65m, had broken the boundaries of what a store could be

Letter: Sir Neil Cossons obituary

In 1971, Neil Cossons and I were on the staff of Liverpool Museum, and he invited me to accompany him on a visit to Ironbridge Gorge in Shropshire. We admired Blists Hill furnace, the bridge, the surrounding buildings and their setting, and shortly afterwards he became its director.The appeal it had as a monument to the industrial revolution lay in it being a complete entity. Many other site-based museums rely on translocating buildings, often into a replicated local landscape. History occurs in places, and Neil knew that raising one’s gaze from the built artefacts to the landscape enables understanding: preserving the place was crucial

‘Women want to experience pleasure’: how the female gaze caught the attention of film, TV and fiction

From passionate romantasy novels to premium television dramas, culture is bringing the agency, desires and interior lives of women to the fore. It’s proving good for business, but is this a permanent revolution?Do you voraciously read the pages of steamy romantasy bestsellers by Sarah J Maas or Rebecca Yarros? Or flood your group chat with breathless recaps of the latest goings-on in TV series such as Heated Rivalry or Bridgerton? Or even immerse yourself in the divisive and challenging cinematic worlds of Emerald Fennell? If so, you surely can’t have failed to notice that in pop culture, the female gaze – storytelling that highlights the meandering, textured, sublimely messy inner worlds and wants of women – is enjoying an explosion.On TV, you can see it everywhere, in the interior lives and desires taken up by Big Little Lies, Sirens or Reese Witherspoon and Kerry Washington’s Little Fires Everywhere. Romantasy harbours it in the shape of powerful maidens and sex in fae (fairy) realms, while Fennell’s Wuthering Heights and Promising Young Woman are marketed with the promise of converting women’s experiences into dark beauty on the big screen.A shift, a moment or a commercial juggernaut? That depends how deeply you look
